Photos: Ending Essential Tremors

Toronto Sunnybrook Health Sciences Centre invited the media, including National Post staff photographer Darren Calabrese on Tuesday to watch as doctors and staff performed clinical trials to help reduce essential tremors on patient Tony Lightfoot. The new technology allows investigators to focus ultrasound waves under MRI guidance through a patient’s skull to reach an area located deep in the brain and the focused ultrasound is then used to lesion the cells that are responsible for the tremors. The new procedure is an alternative to operations that involve cutting open the skull and doing physical surgery on the brain.
